SharpMusique
SharpMusique was a rewrite in C# of PyMusique (written in Python), both programs were iTunes Music Store clients, allowing songs to be downloaded from the iTunes Music Store without DRM. PyMusique PyMusique was written by Travis Watkins, Cody Brocious, and Jon Lech Johansen for the purpose of allowing downloading songs from the iTunes Music Store before DRM was applied to them from a Mac, Linux, or Windows computer. It was first released via Johansen's website on March 18, 2005. Although the iTunes Music Store's method of applying FairPlay DRM to the songs was widely known, PyMusique was the first program to exploit a loophole in the system, allowing users to download songs without the DRM restriction. On March 22, 2005, Apple released an update that rendered PyMusique non-functional. The same day, a new version of PyMusique was released that worked again, only without Windows compatibility. On March 31, 2005, Johansen released SharpMusique, the Windows-compatible port of PyMu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Windows Media Station
Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Media Foundation framework. Overview and features ASF is based on serialized ''objects'' which are essentially byte sequences identified by a GUID marker. The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime File Format, AVI, or Ogg formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives. The most common media contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). The most common file extensions for ASF files are extension (audio-only files using Windows Media Audio, with M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patch (computing)
A patch is a set of changes to a computer program or its supporting data designed to update, fix, or improve it. This includes fixing security vulnerabilities and other bugs, with such patches usually being called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. The majority of patches are provided by software vendors for operating system and application updates. Patches may be installed either under programmed control or by a human programmer using an editing tool or a debugger. They may be applied to program files on a storage device, or in computer memory. Patches may be permanent (until patched again) or temporary. Patching makes possible the modification of compiled and machine language object programs when the source code is unavailable. This demands a thorough understanding of the inner workings of the object code by the person creating the patch, which is difficult without close study of the sourc ...

Python (programming Language)
Python is a high-level, general-purpose programming language. Its design philosophy emphasizes code readability with the use of significant indentation. Python is dynamically-typed and garbage-collected. It supports multiple programming paradigms, including structured (particularly procedural), object-oriented and functional programming. It is often described as a "batteries included" language due to its comprehensive standard library. Guido van Rossum began working on Python in the late 1980s as a successor to the ABC programming language and first released it in 1991 as Python 0.9.0. Python 2.0 was released in 2000 and introduced new features such as list comprehensions, cycle-detecting garbage collection, reference counting, and Unicode support. Python 3.0, released in 2008, was a major revision that is not completely backward-compatible with earlier versions. Python 2 was discontinued with version 2.7.18 in 2020. Python consistently ranks as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Concurrent Versions System
Concurrent Versions System (CVS, also known as the Concurrent Versioning System) is a revision control system originally developed by Dick Grune in July 1986. CVS operates as a front end to RCS, an earlier system which operates on single files. It expands upon RCS by adding support for repository-level change tracking, and a client-server model. Released under the terms of the GNU General Public License, CVS is free software. Design CVS operates as a front end to Revision Control System (RCS), an older version control system that manages individual files but not whole projects. It expands upon RCS by adding support for repository-level change tracking, and a client-server model. Files are tracked using the same history format as in RCS, with a hidden directory containing a corresponding history file for each file in the repository. CVS uses delta compression for efficient storage of different versions of the same file. This works well with large text files with few cha ...

FairPlay
FairPlay is a digital rights management (DRM) technology developed by Apple Inc. It is built into the MPEG-4 Part 14, MP4 multimedia file format as an encrypted Advanced Audio Coding, AAC audio layer, and was used until April 2009 by the company to protect copyrighted works sold through iTunes Store, allowing only authorized devices to play the content. The restrictions imposed by FairPlay, mainly limited device compatibility, have sparked criticism, with a lawsuit alleging antitrust violation that was eventually closed in Apple's favor, and various successful efforts to remove the DRM protection from files, with Apple continually updating its software to counteract such projects. In January 2009, Apple signed deals with all major record labels as well as many independent labels to offer all iTunes music with a DRM-free option. Technicality FairPlay-protected files are regular MPEG-4 Part 14, MP4 Digital container format, container files with an encrypted Advanced Audio Coding, ...
